Abstract

Flight muscle and fat body extracts from Locusta migratoria were incubated with D-[U-14C]-glucose or D-[3-3H]-3-deoxy-3-fluoroglucose and the products were analyzed. In the case of the latter compound, radio-chromatographic analysis yielded glycogen and trehalose fractions that were shown by 19F nuclear magnetic resonance to contain fluorine. Acid hydrolysis of these fractions liberated tritium labelled 3-deoxy-3-fluoro-D-glucose. In addition to the formation of "fluoroglycogen" and "fluorotrehalose" in these tissue extracts, there was an accumulation of tritium labelled fructose.
